Why Mobile TV Does Not Use IPTV
Versatile TV can be watched on a shrewd or 3G cell phone, for example, the LG Vu or Samsung SCH u620 PDA. Both AT&T Wireless and Verizon Wireless deal versatile TV administrations. For Verizon, it is VCAST TV and for AT&T, it iptv UK AT&T Mobile TV. Both AT&T and Verizon Mobile TV use MediaFLO innovations from Qualcomm to communicate the VHF (719 MHz Center recurrence) advanced TV signs to the cell phones. Portable TV administration from various transporter group different arrangement of TV diverts in its transmission (in the scope of 10 to 12 TV directs in an essential bundle).
Portable TV administration doesn't utilize the cell phone organization to send the TV signals. All things considered, it utilizes a different organization to disperse, communicate and communicate the TV signs to the cell phones. It just purposes the cell phone organization to furnish intuitiveness and client approval with the TV specialist co-op. Since the 3G cell phone network from AT&T and Verizon are both able to convey IP traffic, it is by all accounts clear that the least difficult execution for versatile TV is utilizing IPTV. A genuine model is AT&T previously involving IPTV in its U-section administration (web, telephone and TV).
To comprehend the reason why versatile TV doesn't utilize IPTV, the unicast idea of the cell phone network should be made sense of. The present 3G (UMTS, EVDO) cell phone network are intended to convey unicast traffic just, for example highlight point association should be lay out between the client and the Media server for the organization to convey the TV traffic to the cell phone. Since TV is a transmission administration, for example a highlight multipoint association is expected for portable TV administration.

It fundamentally decreases how much transfer speed expected to communicate top notch IPTV content across an organization. This is on the grounds that main a solitary duplicate of each video transfer should be shipped off a switch, which thus makes a duplicate of that stream for the mentioning gadgets. Not in the least does multicast decrease the transfer speed necessities of the organization however the handling force of the Media server can likewise be kept generally low since it just communicates each duplicate of an IPTV stream in turn.
Albeit this 3G portable organization from AT&T and Verizon doesn't have IP multicast, notwithstanding, the following 3G versatile organization update from the two transporters might incorporate the IP multicast include. For AT&T Wireless, the following organization update will be HSPA (High Speed Packet Access) which upholds the MBMS (Multimedia Broadcast Multicast Services) include.
